w9london: totally forgot instant soups. excellent one.
also, why assume no fridge? theres hardly any hotel where you cant get a fridge, especially if u explain its for medical or religious reasons.
btw, you would assume the minicrock pot is impractical, but it really works like a charm and if you get one small enough it wont be a big inconveinence. mine has been to more countries then many people i know and cant even count how many meals its given me!
